Subject: [PATCH 5.15 109/279] net/ipa: ipa_resource: Fix wrong for loop range

From: Konrad Dybcio <konrad.dybcio@...ainline.org>

[ Upstream commit 27df68d579c67ef6c39a5047559b6a7c08c96219 ]

The source group count was mistakenly assigned to both dst and src loops.
Fix it to make IPA probe and work again.

Fixes: 4fd704b3608a ("net: ipa: record number of groups in data")
